Just look at the number of S1 servers available, and notice that largely only the STCC one is regularly populated.
I moved ogHosts #1 to S1 a few days ago - not a soul has entered since.
Consider the mass of racers are S2 licenced and that as of 15 minutes ago only 39 servers, out of all 560 (licenced) had racers in, thats not surprising.
S1 racers roughly fit the statistics when you scale them down - if anything S1 might even have a slightly higher population.
(Too busy to do exact figures atm
)
